Claims. (Gl. 4-218l This invention relates to an improved ventilating mechanism for toilet bowls. More speciiical- 1y the invention embraces a mechanism in the form of an attachment capable of application to conventionally installed water closets.

It is a further object of the invention to provide the Ventilating attachment in such form that it may be installed on conventional water closet bowls without change or modification oi.' the existing installation other than the substitution of the attachment for the conventional seat and cover with which all commercial bowls are equipped.

Additionally it is a purpose and object of the invention to provide a Ventilating attachment that will be economical to manufacture andI install and one that will effectively and eiiiciently remove all objectionable odors from water closet bowls equipped with the invention.

Coming now to a detailed description ot' the invention from which additional advantages will be made to appear, reference will be made to the accompanying drawings wherein like references denote like parts and wherein- Figurel is a plan view of the ventilating attachment taken on a plane just below the water tank of the water closet;

Figure 2 is a fragmentary view in side elevation of the attachment:

Figure 3 is a detail bottom plan view with parts broken away;

Figure 4 is a detail view showing the mounting for the .attachment taken on line l--l of FiB- Figure 5 isa further detail view showing one supporting bracket; and

Figure 6 is a diagram of the motor circuit.

Referring to the drawings, there isshown in Figure 2 a conventional water closet bowl i having a water tank 2 connected to the bowl through the usual connecting pipe 3. In accordance with the present invention, the usual toilet seat and seat cover, normally secured to the bowl by bolts passing through the holes l, are removed, and

the attachment of the present invention is afxed to the bowl by passing the lanchor bolts 5 through the holes .4. The anchor bolts 5 specifi ically shown in Figure 5 are provided with openings 6 that support the pivot bearing rod 'l for the cover 8. The seat 9 is mounted in a manner to be hereinafter described. The cover 8 is provided with the pivot supporting brackets I8. The seat il is provided with the annularly extending channel il having openings I2 extending through the lower face I8 of the seat. The channel I i connects at the rear vend of the seat with the A cover 8.

transverse pipe member i4 rigidly secured to the seat through the medium of the bracket extension the channel il is in free and open communication at all times with the transverse pipe Il,

At either end of the transverse pipe I4 there is provided a socket union member l1 carried by the anchor bolts 8. These members I1 pivotally receive the ends of the pipe member i4. The socket union members il carry bracket arms I8 that extend back and connect with the upper .ends of anchor bolts 8 as shown at i8. The arrangement is such that the seat 8 pivots in the socket members Il. The construction is shown more particularly in Figure 3. l Thel ends of the pipe member Il llt snugly into thes'cket member i1 but are free to pivot therein.

The socket members I1 have attached thereto the rearwardly extending pipes 28. These pipes are connected through a telescopic lmion, indi-` cated generally at 2|, with the second elbow pipe 22. The pipe 22 is enlarged at the free end 23 to telescopically receive in the enlargement the free end o! the pipe 28. A bushing clamp 2|, threadedly carried by the enlarged end 23 of pipe 22, provides a means for securing and sealing the pipe sections 28 and 22 in any given position of adjustment.

The pipes 22 terminate in a motor housing 25. The housing 28 is provided with a suitable supporting bracket 26 for attachment to the room wall at a point below the water bowl 2 (see Figure 2). A duct member'2'l is carried by the motor housing 28 and projects through the wall 28 either into'the interior of a hollow partition having-communication with the exterior or into any suitable stack arrangement. Mounted within the motor housing 25 is a conventional electric motor 28', on the shaft 29 of which is carried the exhaust fan 88.

The motor circuit is controlled by the seat A control switch embracing contact members 8l and 82 (see Figure 6) is normally held by the seat cover 8 and bracket Ill lnvopen position against the tension of the spring 38. This control switch is positioned interiorly of the pipe member i4, as shown in Figures.2 and 4. The circuit wires Il and85 extend from the switch through the pipe member il and thence back through one of the pipes 28 and the associated elbow connection 22 `to connect with the motor circuit in the housing 25. Suitable detachable connections are provided adjacent the telescopic connection between pipe members 2li and 22. 'I'he lead wire 31 for the motor circuit extends to any suitable wall plug or other source of current.

The provision of the telescopic connections between the pipe elements 20 and 22 permits of the attachment being manufactured in a form adapted to be installed upon water closet bowls of varying specific designs and regardless of the particular spacing ofthe bowl from the wall. Additionally it will be observed that the exhaust mechanism is so constructed that it does not, in any way interfere with the plumbing connections Vbetween the bowl i and the water tank 2, en-

abling the attachment to be applied to any conventional water closet bowl with a minimum of eifort and without necessitating any change or modication in the installation.

Most frame buildings have a hollow partition, and the attachment is particularly advantageous forfinstallation in such buildings since the duct 21 can be extended into the hollow partition, and openings either to the exterior or into a well ventilated attic may be fprovided whereby the exhaust gases are at once removed and liberated.

The mode of operation of the device is-believed to be apparent from the foregoing description. However, it may be noted that when the toilet is not in use and the seat cover 8 is in closed position, the motor circuit is opened due to the contact of the bracket I0 with the Contact member 32 yoil the motor circuit control switch. When the cover 8 is raised, the control switch is closed through the medium of the spring 33 which immediately cuts in the motor 28 and drives the exhaust fan 30, creating suction through the pipe connections i4, 20, and 22 directly into the channel I I and from the channel i I through the openings |2 into the interior of the bowl. In this manner it will be observed that there is created an extensive low pressure suction whichwill most effectively exhaust all obnoxious odors in a most eiicient manner.

From the foregoing description it is evident that the present invention provides a very simply and economically constructed attachment for water closets that can be installedl with a minimum of labor and expense, and while the foregoing description is specifimrit is tobe understood that it is merely illustrative and that the invention is comprehended by the appended claims.

-Having thus described my invention, what I claim is:

1. Inan attachment for a water closet bowl, a channeled seat communicating with the interior of the bowl, a motor housing adapted to be mounted on and communicate withA a space behind a wall located rearwardly of the bowl, pipe connections between the motor housing and seat embracing a pivotal mounting for the seat, and telescopic connections in said pipe connections for adjusting the position of the motor housing in relation to the seat.
